Improving frequency and ROCOF accuracy during faults, for P class Phasor Measurement Units [PDF]

open access: yes, 2013
Many aspects of Phasor Measurement Unit (PMU) performance are tested using the existing (and evolving) IEEE C37.118 standard. However, at present the reaction of PMUs to power network faults is not assessed under C37.118.

Toward Perception‐Native Electronic Skin: Bio‐Inspired In‐/Near‐Sensor and Neuromorphic Computing for Humanoid Robots

open access: yesAdvanced Materials Technologies, EarlyView.
Dense tactile streams from across the humanoid body converge on collide in a central wiring and data bottleneck. By relocating computation closer to and then into the skin itself, near‐ and in‐sensor architectures, together with neuromorphic computing, chart a path toward perception‐native electronic skin, in which the conversion of stimulus into ...

Polaritonic Materials: A Comparative Study on the Relaxation Kinetics in Fabry–Perot versus Plasmonic Cavities

open access: yesAdvanced Optical Materials, EarlyView.
Comparing Fabry–Perot and plasmonic nanorod cavities reveals how the number of dark states dictates polariton relaxation. The high number of dark states results in a polaritonic bottleneck, while reducing the number of dark states enables to measure the polaritonic decay.

Multiobjective Codesign Optimization of a Planar Pneumatic Artificial Muscle‐Based Snake‐Like Robot for Enhanced Agility and Energy Efficiency

open access: yesAdvanced Robotics Research, EarlyView.
A codesign multiobjective optimization framework was developed to enhance the morphology and controller of a snake‐like robot driven by artificial muscles. It improved planar locomotion, agility, and power efficiency. The approach optimized link geometry and controller gains, revealing that shorter muscles near joints and longer linkages maximize ...

Algebraic Diagnostics for Instantaneous Frequency Estimators

open access: yes
Abstract Tracking instantaneous frequency (IF) in multi-component signals, phase-locked loops (PLLs), and reduced-order power-system models is frequently undermined by severe numerical ill-conditioning near regime boundaries. Conventional time--frequency transforms and signal-space geometric invariants can become unreliable precisely ...

Discrete instantaneous frequency (DIF) estimation

open access: yes, 1996
Signals arising from practical or natural systems are often non-stationary. There are many methods to analyse non-stationary signals. Time-frequency analysis is one of the most popular techniques used for its analysis in recent years.

Nonlocomotory Robotic Strategies for Dynamic Rotation Control in Terrestrial Robots: A Review

open access: yesAdvanced Robotics Research, EarlyView.
Terrestrial robots increasingly require rapid body rotation to maintain stability and agility in complex environments. This review shows nonlocomotory rotational control strategies that operate without ground contact, including reaction wheels, tails, bars, limbs, and thrusters.
